Burned Tripe

I am a regular shopper at pick n pay but what I got today disgusting. I bought pnp cooked tripe pk for R 47. 99 so that me and my family could have it for super. When I got home I put the tripe in a macro oven to pre heat I was amazed buy the smell of the tripe it was smelling like burned we tried eating it but we could not because it was tasteless and burned to the point that even the staff in the kitchen could not eat it. My question is why did the staff in the kitchen sell that tripe to customers when is smelled and tested like that (burned). I still have the tripe in my fridge with a full package as a proof. I need my money back.
